Ok, for me it seems strange this noise... All the car I drove I never hear this kind of sound when I change the gear or when I'm slipping the clutch. I will come back tomorrow night on this forum after to see the dealer...
I will try to drive another gt86 to check if this sound is also there... |

Yeah I am braving the dealer as well. My honk has recently gotten worse and will now occasionally do it in 3rd and 4th gear. Definitely not normal and seems weird and unlikely to be a frequency resonance issue as 5% clutch engagement wouldn't add or eliminate a specific frequency range and its only in select gears or speed. We will see. Hopefully it won't be another crickets type thing

So, I just come back to the dealer. He heard the noise and He kept the car all the day to find the problem. He said that they didn't see any mechanical problems... they put some oil/grease in some service opening around the clutch and transmission but when I did the same test I heard the same noise...
I wrote a mail to the dealer with my detailed observations... I hope that he will transfer my observation to Toyota France... fingers cross... |

Thanks Yoyo - keep us up-to-date on what you and the dealer/Toyota of France find.

Just got it back this morning. They replaced my fuel pump and adjusted the clutch grab and it seems to have fixed it strangly enough. Or at least minimized it. It's definitely quieter but the weather here isn't as cold so I'm not sure if there is a correlation. The service techs weren't either. If I still hear it I'm going to put it on jack stands or a dyno and get underneath to figure out where it's coming from

Great, thanks for the tip! The fuel pump might make sense, because I noticed that it always occurs when adjusting the clutch with the accelerator depressed.

Couple of things?
1) I'm curious, how many of you did the "clutch" adjustment as seen on this forum? The reason I ask is that you may have I advertantly lowered it too much and because the motion ratio doesn't change, it's causing your clutch to not fully disengage when pressed-slightly dragging but not enough to cause issues at stop lights or anything. 2) I completely disagree with the rep that said its straight cut gears! They are extremely loud and only used for racing and sometimes reverse-hence the whining sound when backing up. Street cars will always come with helical cut gears. But otherwise I'm curious of what is causing this too. I have 17k and knock on wood no sound yet. |

I did not do the clutch adjustment. Also, an edit to my post above saying the problem is essentially gone for me. The problem has significantly lessened (perhaps due to change in weather), but, I do get still get the noise when I'm sloppy on my shifting. |

It's only happening when you slip the clutch a bit. I've been adjusting my shifting to avoid my noise, but other owners I know out here don't have the noise when they shift.
Someone said it was the clutch delay valve. Has anyone talked to the dealer about that and had theirs replaced to see if the noise went away? It could be a faulty valve emitting the noise when you slip the clutch too much. If the valve is off a certain degree the movement of the fluid could cause some unintended pressure that would cause an audible noise.
